the new one should do all that the older one can
The 500 goes down in size to 4 mm and up to 10 mm. The 700 goes from 8 mm to 14 mm. There is some overlap but the 700 plunges deeper also. They are complementary not the same. It would be inappropriate to use the 700 for cabinets or the 500 for gates/doors.
